The blobfinder model simulates a color-blob-finding vision device, like a CMUCAM2, or the ACTS image processing software. It can track areas of color in a simulated 2D image, giving the location and size of the color 'blobs'. Multiple colors can be tracked at once; they are separated into channels, so that e.g. all red objects are tracked as channel one, blue objects in channel two, etc. The color associated with each channel is configurable.
